If you can't stand to have a "pedestrian" .270 [hey I have a couple of them, assigned to my kids] or if you hate J O'C just step up to the .280 Rem which has a great selection, and you have a (small) chance of finding fodder for it in east bumf--- nowheres. Overall, I have found a great selection of high SD, and high BC, even moderately priced, hunt-worthy stuff in 284 and 338.
Or for a bit of humor, and you want a wildcat with some history, get a .338-06 (aka .33 OKH) and if your ammo gets lost, use .30-06 and you will have decent accuracy to about 10 feet. There is even a youtube video on the topic.
